Stock coil or should it be changed? Points to Electroni #284832 04/11/09 04:41 PM 04/11/09 04:41 PM

My question is, will I need to buy a new coil or can I use the old existing one? I thought I read it needed to be changed for one compatible with electronic ignition? If so, Can I just get one from a 73 Chrysler or something that originally had electronic ignition or will I need a performance one? What do you guys recommend? This is not a race car, just a sunday cruiser...stock 383 with a 2-bbl. Thanks!

I'd get the 1.25 ohm ballast & I would highly suggest that you get the MP chrome box instead of the orange ecu even if it means you buy the dist/harness/ecu seperately instead of the orange box complete pkg. EDIT if you do change coils yes a 73 up stock one will be fine as you would have exactly the same as a factory oe 73 up setup but unless you had one in your stash you might get a hotter one such as a msd blaster 2(which MAY change the ballast requirements) but your stock coil will work fine.

I'm not sure which ohm ballast is currently on my car, I would assume a stock one. Just trying to set myself up with all the right parts while waiting for my kit to show up.

I am buying a set from a member here, its new in the box, never used.

Upgrade ballast resistor to 0.25 Ohms Next when setting the timing, note that the Mopar distributor has 20 degrees and you should set the inital advance @ 14-16 degrees. Making a total of 34-36 degrees. Just my $0.025..

Because the Blaster has higher output voltage and can handle a higher input voltage, when using a 0.25 Ohm vs the 1.25 Ohms the coil sees a higher voltage. Just my $0.025..

Thanks for the help, just to clarify, if using the stock point type coil currently on my car, just use the 1.25 OHM resistor that comes with the kit, if I use the Mopar Blaster coil, use the .25 ohm resistor. The purpose of the Mopar blaster coil and .25 ohm resistor is for a hotter spark? Better performance? As mentioned, this car is all stock, 2-brl carb, 383, automatic. Not a race car by any means.

I put one on a smogger 440 once, which you would think would need all the spark help it could get, and it made no difference on my seat-o-pants meter.

I guess the hundreds of thousands of Chryslers that ran for hundreds of thousands of miles using the el crapo Chrysler ignition were just, lucky? I put on of these in my '70 soon after they came out in, when, 72? I owned that car up into the '80's. Later, I ran a 340 in my old FJ40 Landcruiser, and guess what? I ran an el crapo Chrysler ECU in that too!! Last time it ran, it ran with the el crapo ECU

Last time it ran, it ran with the el crapo ECU Yeah but why add in all the extra wiring and clutter when the pertronix will keep it clean, simple and stock looking and do just as good of a job at it?

And also use some washers behind it to raise it off the firewall so it will have some air movement behind it. 5159057-Sept07picts020.jpg (64 downloads)
